Cleaned up and used macro magic to shorten the INST_* macros

Browse Source 
Instead of having 3 differing macros for each typed version of each
opcode, just supply the type as a symbol to the macro, which will
concatenated the type to all the places necessary.

Relies on D(BYTE|HWORD|WORD) and OP_*_(BYTE|HWORD|WORD) being a
consistent naming style.
